vredina [299]

Answer:

$\bar X= \frac{\sum_{i=1}^n X_i}{n}$

The reason is because we assume that each week have the same weight and replacing we got:

$\bar X= \frac{190+163+327+205}{4}= 221.25$

And the best option would be:

D. 221.25

Step-by-step explanation:

For this case we have the following data given

Week 1 2 3 4

Minutes 190 163 327 205

For this case we can find the mean with the following formula:

$\bar X= \frac{\sum_{i=1}^n X_i}{n}$

The reason is because we assume that each week have the same weight and replacing we got:

$\bar X= \frac{190+163+327+205}{4}= 221.25$

And the best option would be:

D. 221.25

babunello [35]

Answer:

$r^{3}=4050$

r = ∛4050

Step-by-step explanation:

$V=\frac{4}{3} \pi r^{3}$

$5400=\frac{4}{3} \pi r^{3}$

$r^{3}=3(\frac{5400}{4} )$

$r^{3}=3(1350 )$

$r^{3}=4050$
